The Jammafier with serial number 100 marks the end of general availability of the Jammafier for now. Due to real-life obligations (just had my first kid), spending hours and hours in a single sitting to assembling these is just not on the table right now.
I hope to have them back in stock in the future if there is still demand (send me a message!), but it won't happen for a few months, realistically we're looking at 2020. The JVS-PAC 2's are a different story, as they are professionally assembled by a 3rd party. This will also be how new Jammafiers will be made. One of the reasons I don't do this right away is that all available funds and time will be used towards making the Retro Scaler A1 finished and available - and pending how much time I got available, I hope to have it 'out' in 2019.
